Title: Improvements in control rod drive mechanisms for nuclear reactors
IPC: G21C7/20
Filed: 1960-07-20
Abstract: 932,240. Controlling reactors. GENERAL DYNAMICS CORPORATION. July 20, 1960 [July 28, 1959], No. 25362/60. Class 39 (4). A control rod drive includes a reversible electric motor with a biasing arrangement to prevent the rod from drifting out of position under the influence of a steady force such as gravity. Fig. 5 shows a control circuit for a two-phase motor 38. Opening switches 43, 49 moves the control rod up and down respectively. An adjustable biasing resistance 45 causes a small phase difference between the coils of the motor, producing a slight torque tending to raise the control rod. The right-hand part of Fig. 5 shows an arrangement of microswitches for limiting the travel of the rod. Fig. 1 shows part of the mechanism, including an electromagnetic coupling at 21, 22 and orifices of differing sizes at 15, 16, 17. One face of the coupling is curved to prevent sticking due to residual magnetism, and the orifices provide increasing braking, by throttling the outflow of liquid moderator, as the control rod falls. A potentiometer is provided as a position indicator. U.S.A. Specification 2,779,728 is referred to.

Patent GB-414234-A (GB)
Title: Improvements in or relating to the manufacture of porous rubber
IPC: C08J9/26
Filed: 1933-09-20
Abstract: An aqueous rubber, gutta, or like dispersion is coagulated in the presence, in distribution through the mass, of grains of a pore-forming core material, which material is capable of remaining solid at normal temperatures and is soluble or colloidally dispersible by action of hot water or prolonged action of cold water upon it, and thereafter extracting the core material.  The process is particularly applicable to the production of moulded articles.  The dispersions may be natural or artificial, and may be in the form of concentrated or diluted latex.  The core material may be a reversible colloid, e.g. glue, gum arabic, agar-agar, gelatine, gum tragacanth, or dextrin, or molasses or other sugar substances; or a product of the partial hydrolysis of starch or cellulose such as that obtainable from bleaching residues.  Or the grains may be formed partly of these materials and partly of an inert powder, e.g. talc, kaolin, calcium carbonate.  The dispersion may contain vulcanizing agents, accelerators, antioxidants, and minerals or other softeners.  The grains may contain or be coated with a coagulant, e.g. a heat-destabilizing agent such as magnesium or calcium sulphate, or di-substituted aromatic guanidines, or ammonium salts in conjunction with zinc oxide, or heat-destabilizing agents may be added to the dispersion.  The rubber dispersion may be unvulcanized or pre-vulcanized.  Vulcanization may occur when the temperature is raised to cause coagulation, or the temperature may be further raised after coagulation, or the hot water used to extract the core material may effect vulcanization.  The dispersion may be poured into a mould containing the core material, or the latter may be mixed with the dispersion before application to the mould.  The mould may be made of material incapable of withstanding the usual high temperatures of vulcanization, e.g. wood or plaster of paris.  Examples are given illustrating the making of the grains or pellets and the treatment of mixtures of pellets and dispersions; according to Example III, the latex may be mixed with an aqueous emulsion of mineral oil.

Title: Gas turbine engine combustion chamber
Inventor: SMITH HERBERT FRANK
IPC: F23R3/42
Filed: 1965-06-21
Abstract: 1,073,335. Gas turbine combustion chambers. ROLLS-ROYCE Ltd. June 21, 1965, No.26207/65. Headings F1G and F1L. A combustion chamber 17 for a gas turbine engine comprises a casing 14 having an inlet 21 for receiving air from a compressor of the engine and an outlet 22 for supplying combustion gases to a turbine of the engine, both the inlet 21 and outlet 22 being disposed at an inner portion only of the engine; at least one flame tube 24 which is mounted within and spaced from the casing 14, the whole of the or each flame tube 24 being disposed outwardly of the inlet 21, the upstream end of which is disposed forwardly of any portion of the or each flame tube 24; and means 42 for supplying fuel to the or each flame tube 24, a portion only of the air passing through the inlet 21 being directed around and into the or each flame tube, and the remaining portion of the air being passed directly through the combustion chamber 17 to the outlet 22 without any substantial change in the direction of flow. Preferably, at least a substantial part of the flame tube 24 is disposed rearwardly of the downstream end of the outlet 22. The combustion chamber 17 shown is an annular chamber having a single annular flame tube. The inlet 21 comprises guide vanes 31, 32, 33 which direct some of the incoming air into an annular combustion air duct 25 and the remainder into an annular dilution air duct 34. The air duct 25 extends along the radially outer side of the flame tube 24, the wall 26 of the latter having inlet apertures 27 through which the combustion air from the duct 25 enters the flame tube 24. The combustion air duct 25 communicates with a cooling air duct 30 which extends along the radially inner side of the flame tube 24, the duct 30 receiving some of the air passing through the duct 25. Fuel is injected into the flame tube 24 through a plurality of angularly spaced apart injectors 42 which are supplied with fuel from an annular manifold. A plurality of angularly spaced apart hollow members 35 are mounted in the combustion chamber 17, each having apertures 36 in its wall through which dilution air from the dilution air duct 34 passes, also an inlet 40 which communicates with the outlet of the flame tube 24 so as to receive the combustion products and an outlet 41 which communicates with the outlet 22 of the combustion chamber 17. Thus the dilution air passes substantially axially through the combustion chamber 17 without its direction of flow being reversed, only the combustion and cooling air being reversed in direction. Accordingly pressure losses resulting from reversals of flow are minimized. This design of combustion chamber permits the axial length to be reduced at the expense, however, of increased engine diameter in the region of the combustion chamber. This reduction in axial length permits the engine to be mounted vertically within the wing of an aircraft to provide vertical lift. The engine may be of the by-pass type with the casing 14 forming the inner wall of the by-pass duct of the engine.
